(Updated) Microsoft 365 Copilot: Copilot chats in search results

Microsoft 365 Copilot will integrate historical Copilot chats into Microsoft Search, allowing users to retrieve past interactions from notebooks, agents, and the main chat via a new "Copilot Chats" data source. This feature requires a Copilot license and will roll out worldwide from November to December 2025.

Updated December 8, 2025: We have updated the timeline. Thank you for your patience. 

We’re introducing a new capability that enhances Microsoft Copilot by integrating historical Copilot conversations into Microsoft Search. This update allows users to retrieve past interactions—including chats from notebooks, agents, and the main Copilot chat interface—directly within the search results page (SERP). A new “Copilot Chats” data source will also appear in the right rail, enabling users to scope their search specifically to Copilot-generated content.

A Microsoft 365 Copilot license is required to access this feature.

This message is associated with Microsoft 365 Roadmap ID 506751.
